Deep-water contactless trigger switch

Abstract

The invention belongs to the field of deep-sea technologies and relates to a deep-water contactless trigger switch. The deep-water contactless trigger switch comprises a solid state electronic contactless switch element and a switch body, wherein the solid state electronic contactless switch element is sealed in the switch body. The deep-water contactless trigger switch is characterized by further comprising a small watertight connector, a front end cover, an O-shaped sealing ring, a back end cover and a magnet; axial and radial dual-seal structures are adopted on the contact place of the front end cover and the switch body and the contact place of the back end cover and the switch body, and the axial direction and the radial direction are both sealed by the O-shaped sealing rings. According to the deep-water contactless trigger switch, the problem of deep-sea high-pressure sealing is effectively solved, so that the deep-water contactless trigger switch is safe and reliable; a deep-sea small watertight connector allowing wet plugging under the water is provided for adapting to requirements of the deep-water severe environment, and the maximum working water depth is up to 14000 m; the deep-water contactless trigger switch can be applied to multilayer trawling of abyssal plankton and deep-sea detection and sampling devices, such as submarine sediment acoustics in-situ detection systems.

Description

technical field [0001] The invention belongs to the field of deep-sea technology, in particular to a deep-water non-contact trigger switch used on a deep-sea detection instrument and a sampling device. Background technique [0002] Entering the 21st century, countries around the world are developing rapidly in the field of deep-sea technology, and China has developed particularly rapidly in deep-sea technology such as deep-sea detection instruments and sampling devices. A trigger switch is needed, but most of the existing trigger switches adopt a mechanical operation mode, which has relatively large operating force, difficult operation, and low reliability. The Chinese patent No. 201220336210.4 discloses a single-wire non-contact limit switch, which uses technologies such as bidirectional thyristor and its trigger circuit to solve the problems of multiple wiring, complicated production, and low reliability, but still has poor versatility, problems such as narrow scope of ap...
